feat(guard): wire Doors B and C to the real guard (Phase 2 step 4)
Adds llm_ingestion_guard>=0.2,<0.3 as this library's first and only runtime dependency, and guard_adapter.py -- the one module that imports it. The flows themselves are unchanged: they still take an injected gate, and importing the package still does not import the guard, so a Door A consumer is unaffected by the dependency's state. Door B screens the exact bytes it persists. The guard's §6 bookends (prepare_input -> model -> screen_output) assume a model call in between; this library makes none, and prepare_input returns prompt-shaped text (sanitized AND spotlight-fenced with a per-call nonce) that must never reach disk. So the adapter calls screen_output alone, on the extracted text as it stands, and hands that same text back -- the verdict is then a statement about the bytes actually written. This supersedes the plan's "bookends" wording, recorded there under "Settled during implementation (step 4)". It follows that the gate refuses rather than repairs: a file carrying an invisible carrier is rejected, not stripped and persisted. Sanitizing first would write a document differing invisibly from the operator's file while source_sha256 still points at the original bytes. Operator decision; the policy is PRESET_USER_UPLOAD, so any finding at all is held back. Door C hands the bundle over whole to okf.import_bundle, which resolves the cross-link graph across concepts. Per-concept reasons are derived from the scan findings (severity:label) because stamp_concept keeps the disposition and drops the reason strings behind it. Assumption B1 closes as a signature smoke test over what the adapters actually call -- screen_output and okf.import_bundle signatures, the Disposition values both doors compare by value, the Origin/Channel vocabularies Door C validates, the result fields read, and the upload preset's shape. prepare_input is not pinned: drift there cannot reach this library. Behaviour is pinned against the real scanner too, including the persist-gate proof that a fail-secure fixture leaves the bundle byte-identical. B2 closes with it: git+https tag install over anonymously readable HTTPS, no credential. A direct reference is an install-time channel, not the pin -- the range stays in pyproject, is satisfied by the tag install today, and resolves normally once the package index exists. A packaging test enforces that the guard remains the only runtime dependency (verified by hand-mutation).

### What is gated today: read this before trusting a door
|
||||
|
||||
The package still has **zero runtime dependencies** and imports no guard
|
||||
function anywhere. That has a direct consequence for what "gated" means here:
|
||||
|
||||
- **Door A (`materialize_bundle`) is ungated.** It calls nothing before
|
||||
writing to disk and writes what it is given.
|
||||
writing to disk and writes what it is given. A caller materializing

untrusted content is responsible for gating it.
|

- **Doors B and C (`process_inbox`, `import_bundle`) gate through an adapter
|
||||
you supply.** Each takes a `gate` argument; the flow hands it the content
|
||||
you pass in.** Each takes a `gate` argument; the flow hands it the content
|
||||
and obeys the verdict, refusing to persist anything that does not clear the
|
||||
guard's non-blocking floor — including a disposition it does not recognise,
|
||||
and (at Door C) a concept the gate returned no verdict for. What it cannot
|
||||
do is check that your adapter is a real guard. A permissive stub approves
|
||||
do is check that your adapter is a real guard: a permissive stub approves
|
||||
everything, and the flow will believe it.
|
||||
|
||||
So gating remains **your** responsibility at the call site: pass an adapter
|
||||
over `prepare_input`/`screen_output` (Door B) or `okf.import_bundle`
|
||||
(Door C). Wiring the doors to the real guard, and pinning it as a dependency,
|
||||
is step 4 of phase 2 and is not done yet.
|
||||
`llm_ingestion_okf.guard_adapter` is the adapter over the real guard, and the
|
||||
only module here that imports it — importing the package itself does not:
|
||||
|
||||
This is stated plainly because earlier wording ("calls the guard at every
|
||||
persist gate") described the intended end state in the present tense, and a
|
||||
consumer reasonably read it as safe-by-default.
|
||||
```python
|
||||
from llm_ingestion_okf import process_inbox
|
||||
from llm_ingestion_okf.guard_adapter import inbox_gate
|
||||
|
||||
result = process_inbox(inbox_dir, bundle_dir, "2026-07-25T12:00:00Z",
|
||||
okf_type="reference", gate=inbox_gate)
|
||||
```
|
||||
|
||||
Two properties of that adapter are worth knowing before you rely on it.
|
||||
It screens the **exact bytes it persists** — the guard's `prepare_input`
|
||||
bookend prepares text for a model call, which this library never makes, so
|
||||
only `screen_output` is used and the screened string is the written string.
|
||||
And it **refuses rather than repairs**: a file carrying an invisible
|
||||
zero-width or bidi character is rejected, not silently stripped and written.
|
||||
Door B screens under the untrusted-upload policy, so any finding at all is
|
||||
held back rather than persisted.

||||
This section is stated plainly because earlier wording ("calls the guard at

targets Node/ESM with zero npm dependencies.

Python 3.10+, and exactly one runtime dependency — the security boundary,

A git URL is a PEP 508 direct reference and pins one exact tag, so it is an
|
||||
install-time *channel*, not the pin: the range above stays the declared

dependency and resolves normally once the package index exists. The optional

`[extract]` extra (pdf/docx/xlsx parsers) is not populated yet. The planned

### Settled during implementation (step 4)
|
||||
|
||||
- **Door B calls `screen_output` alone, and this supersedes deliverable 3's
|
||||
"`prepare_input`/`screen_output` bookends".** The bookends assume a model
|
||||
call between them; this library makes none, and `prepare_input` returns
|
||||
prompt-shaped text (sanitized *and* spotlight-fenced with a per-call nonce)
|
||||
that must never reach disk. The adapter therefore screens the extracted
|
||||
text as it stands and persists that same string, so the verdict is a
|
||||
statement about the bytes actually written.
|
||||
- **The gate refuses; it does not repair.** Sanitizing before persisting
|
||||
would write a document differing invisibly from the operator's file while
|
||||
`source_sha256` still points at the original bytes. A file carrying an
|
||||
invisible carrier is rejected instead — the guard's own doctrine is that a
|
||||
carrier has no legitimate place in a reference file, and this library's
|
||||
posture everywhere else is fail-fast, never repair. Operator decision.
|
||||
- **The policy is `PRESET_USER_UPLOAD`** (untrusted tier, quarantine floor):
|
||||
an inbox drop is an untrusted upload, so any finding at all is held rather
|
||||
than written. A caller needing another tier injects their own adapter.
|
||||
- **`guard_adapter.py` is the only module that imports the guard**, and the
|
||||
package `__init__` does not import it, so a Door A consumer's import path
|
||||
is unaffected by the dependency's state.
|
||||
- **Assumption B1 pins what the adapters call, not the whole guard.**
|
||||
`prepare_input` is dropped from the smoke test: drift there cannot reach
|
||||
this library. What is pinned: `screen_output` and `okf.import_bundle`
|
||||
signatures, the `Disposition` values both doors compare against, the
|
||||
`Origin`/`Channel` vocabularies Door C validates, the result fields the
|
||||
adapters read, and the upload preset's shape.
|
||||
- **The pin stays a range; the git URL is an install channel.** A PEP 508
|
||||
direct reference pins one tag and cannot express `>=0.2,<0.3`, but it is an
|
||||
install-time channel rather than a dependency declaration: the range is
|
||||
what `pyproject.toml` carries, it is satisfied by the tag install today,
|
||||
and it resolves normally once the package index exists (confirmed by the
|
||||
guard repo, superseding an earlier reading that the range had to go).
|
||||
- **Door C reasons are derived, not carried.** The guard's `stamp_concept`
|

keeps a concept's disposition and drops the reason strings behind it, so

the adapter reports `severity:label` per finding — the audit trail actually

Doors B and C take an INJECTED gate so the flows stay dependency-free and

the real guard. It translates in one direction only — guard verdict in, the

door's decision type out — and takes no decision of its own. Everything a
|
||||
verdict depends on happens inside the guard.
|
||||
|

**Door B screens the exact bytes it persists.** The guard's §6 bookends
|
||||
(`prepare_input` -> model -> `screen_output`) assume a model call in between;
|
||||
this library makes none, and `prepare_input` returns prompt-shaped text
|
||||
(sanitized AND spotlight-fenced with a per-call nonce) that must never reach
|
||||
disk. So the adapter calls `screen_output` alone, on the extracted text as it
|
||||
stands, and hands that same text back. Two consequences, both deliberate:
|
||||
|
||||
- an invisible carrier is REFUSED rather than stripped-and-persisted. The
|
||||
guard's own doctrine is that a carrier has no legitimate place in a
|
||||
reference file, and sanitizing before persisting would write a document
|
||||
that differs invisibly from the operator's file while `source_sha256`
|
||||
still points at the original bytes. This library validates and refuses;
|
||||
it does not repair.
|
||||
- the verdict is a statement about the persisted document, because the
|
||||
screened string and the written string are the same string.
|
||||
|
||||
The policy is `PRESET_USER_UPLOAD`: an inbox drop is an untrusted upload, so
|
||||
any finding at all is held for review rather than written. A caller who needs
|
||||
another tier writes their own three-line adapter — that is what the injected
|
||||
seam is for.
|
||||
|
||||
**Door C hands the bundle over whole.** `okf.import_bundle` resolves the
|
||||
cross-link graph across concepts, so gating them one at a time would throw
|

half the gate away. The adapter maps each `ConceptResult` to an

|
||||
|
||||
Steps 3 and 5 exercised the flows against test doubles; this suite wires the
|
||||
pinned dependency in and pins two different things:
|
||||
|
||||
- **the surface (assumption B1).** `test_guard_*` reads the guard's actual
|
||||
signatures, enum values and result fields, and compares them against the
|
||||
constants the library branches on. These tests are the upgrade-drift alarm:
|
||||
they fail when the dependency moves under us, which is the only way a
|
||||
by-value comparison (`"warn"`) can be kept honest without importing the
|
||||
enum into the flow modules.
|
||||
- **the behaviour.** A benign fixture persists; a fixture the guard fails
|
||||
secure on leaves the bundle byte-identical. Verdicts here come from the
|
||||
real scanner, so these are the tests that would notice the adapter passing
|
||||
the wrong text, the wrong policy, or the wrong direction of the branch.
|
||||
|
||||
The adapters are deliberately thin, and that is the point: everything a
|
||||
verdict depends on happens inside the guard.
